He writes contracts, objections, articles, books and has blogged in the past. As a public procurement trainer, he can explain to people where common sense is found in the law. He is a recognised expert in public procurement, promoting the application of innovative practices in this area, including social and environmental aspects. He is also a co-founder of the Slovak APUeN.
